@johnou the 2.0 branch is just being maintained for an ONOS release. We're currently just fixing some minor bugs in the Raft code for our release and cherry picking them into master. The last bit of major refactoring to 2.1 will be merged into master today or tomorrow, and the 2.0 branch will all but die once our release is done since we'll be upgrading to 2.1 in our next release.
